Several proven methods can reduce menstrual flow, ranging from over-the-counter pain relievers to hormonal options that can cut bleeding by 80% or more. The right approach depends on how heavy your periods are, whether you want hormonal or non-hormonal options, and whether you’re also looking for contraception.
A normal period produces about 30 to 40 ml of blood per cycle. Bleeding becomes clinically “heavy” above 80 ml per cycle, which roughly translates to soaking through a pad or tampon every two hours, passing clots the size of a quarter or larger, or bleeding for more than seven days.
Over-the-Counter Anti-Inflammatories
Ibuprofen and naproxen do more than relieve cramps. They block the production of prostaglandins, hormone-like chemicals that trigger your uterine lining to shed. Higher prostaglandin levels are directly linked to heavier bleeding, so reducing them also reduces flow. In clinical trials, naproxen cut menstrual blood loss by about 30% compared to placebo, while ibuprofen reduced it by roughly 25%.
Timing matters. These medications work best when you start taking them just before your period begins or on the first day of bleeding and continue through the heaviest days. If you wait until day three, you’ve already missed the window when prostaglandin levels spike. This approach is especially useful if you want a simple, non-hormonal option that also handles pain.
Hormonal Methods
Hormonal options are the most effective medical approach for reducing flow. They work by thinning the uterine lining so there’s less tissue to shed each cycle. Some methods can reduce or eliminate periods entirely.
Hormonal IUD
A hormonal IUD that releases a small amount of progestin directly into the uterus is the single most effective option for reducing heavy periods. Studies show it reduces menstrual blood loss by about 80% within six months, and many people eventually have only light spotting or no period at all. Because the hormone acts locally, the systemic side effects tend to be milder than with pills. It also lasts several years, making it a low-maintenance choice.
Combined Hormonal Options
Combined birth control pills, patches, and vaginal rings contain both estrogen and progestin. They prevent the uterine lining from building up as thickly each month, which directly reduces flow. Oral progestins alone reduce bleeding by roughly 55 to 60% over six months. Combined methods typically fall in a similar range. You can also use continuous cycling, skipping the placebo week to avoid withdrawal bleeding altogether.
Other Progestin-Only Options
The hormonal implant and the injectable progestin shot both suppress the uterine lining. Many people on the shot stop having periods entirely after a few cycles. The implant causes unpredictable bleeding patterns in some users, but for others it significantly lightens or stops periods. These are worth discussing with a provider if you prefer a longer-acting method but don’t want an IUD.
Non-Hormonal Prescription Treatment
If you want something stronger than ibuprofen but don’t want hormones, there’s a prescription medication that works by stabilizing blood clots. Your body naturally forms clots to slow menstrual bleeding, but an enzyme called plasmin breaks those clots down. This medication blocks plasmin, helping clots hold together longer and reducing overall blood loss. It’s taken only during your period, typically for up to five days during the heaviest bleeding.
This option works well for people who can’t use hormonal methods due to medical reasons or personal preference. It doesn’t affect your cycle length or timing, just the volume of bleeding.
How Body Weight Affects Flow
Carrying extra weight can make periods heavier through a biological mechanism that goes beyond just hormone levels. Research from the Journal of Endocrinology found that a higher BMI is associated with delayed repair of the uterine lining after it sheds. Normally, your endometrium quickly rebuilds its surface to stop bleeding. In animal studies, subjects on a high-fat diet had significantly slower endometrial repair and higher levels of inflammatory markers in uterine tissue. That delayed healing translates to longer, heavier bleeding.
The uterine lining in subjects with higher body weight also showed reduced cell proliferation, the process that closes the wound left by shedding. This creates a more pro-inflammatory local environment during menstruation. Weight loss can potentially reverse this effect, though the research is still establishing how much weight change is needed to see a meaningful difference in flow.
Nutrients and Supplements
You may have heard that iron supplements can reduce heavy bleeding. A randomized clinical trial tested this directly: 50 mg of elemental iron taken during the first four days of menstruation did not change bleeding volume in non-anemic women. However, being deficient in iron or vitamin D may worsen menstrual irregularities, including heavier flow. The takeaway is that supplements won’t reduce an already-normal or heavy flow, but correcting a deficiency might prevent it from getting worse.
Iron-rich foods consumed during menstruation were associated with slightly lower bleeding scores in some studies, though the effect was modest. If you’re losing a lot of blood each cycle, replacing that iron through diet or supplements is still important for preventing anemia, even if it doesn’t reduce the flow itself.
Herbal Remedies
Shepherd’s purse is a traditional remedy for heavy menstrual bleeding, but there is no strong scientific evidence that it works on its own. One clinical trial found that taking shepherd’s purse extract alongside an anti-inflammatory slightly reduced bleeding more than the anti-inflammatory alone, but the effect was small. Ginger has been studied for menstrual pain more than for flow reduction, and reliable data on its impact on bleeding volume is limited. If you try herbal approaches, treat them as a possible complement to proven methods rather than a replacement.
Procedures for Severe Cases
When medications don’t provide enough relief, minimally invasive procedures can help. Endometrial ablation destroys the uterine lining using heat, cold, or other energy sources. It’s an outpatient procedure with a relatively quick recovery, and most people see a dramatic reduction in bleeding. Some stop menstruating entirely. The tradeoff is that it affects future fertility, so it’s typically reserved for people who are done having children.
For heavy bleeding caused by fibroids, uterine artery embolization is an option that cuts off blood supply to the fibroids, causing them to shrink. Compared to surgical fibroid removal, it involves less blood loss during the procedure, shorter hospital stays, and faster return to normal activities. Both approaches significantly improve symptoms, and rates of complications and repeat procedures are similar, around 7 to 9%.
Choosing the Right Approach
Your best starting point depends on how heavy your periods are and what you’re comfortable with. For mildly heavy periods, taking ibuprofen or naproxen starting on day one of your cycle is the simplest intervention. If that’s not enough, a hormonal IUD offers the most dramatic reduction with the least daily effort. Non-hormonal prescription options fill the gap for people who want more than an anti-inflammatory but fewer systemic effects than hormones.
If your flow soaks through a pad or tampon every hour for several consecutive hours, or you’re passing clots larger than a quarter, that level of bleeding warrants a medical evaluation. Heavy periods can be caused by fibroids, polyps, clotting disorders, or hormonal imbalances, and identifying the underlying cause shapes which treatment will actually work.
